Question

我无法在同一个Java Web应用程序中使用restlet服务器和客户端jar。问题是一些服务器和客户端的jar具有相同的名称。如果我尝试删除重复的jar，我会收到类似

的错误

java.lang.NoSuchMethodError: org.restlet.Context.getClientDispatcher()Lorg/restlet/Restlet;
  org.restlet.resource.ClientResource.createNext(ClientResource.java:503)
  org.restlet.resource.ClientResource.getNext(ClientResource.java:829)
  org.restlet.resource.ClientResource.handleOutbound(ClientResource.java:1221)
  org.restlet.resource.ClientResource.handle(ClientResource.java:1068)
  org.restlet.resource.ClientResource.handle(ClientResource.java:1044)

  org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:432)
  javax.servlet.http.HttpServlet.service(HttpServlet.java:754)
  javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

我的方案是，我的Web应用程序可以作为Web服务客户端和服务器。所以我正在寻找一个选项，我可以在同一个Web应用程序中使用restlet客户端和服务器jar。我已经搜索了网络，但没有找到任何可行的解决方案。

感谢您的帮助。

事实上，Restlet的核心jar支持客户端和服务器端。也就是说，扩展名（名称为org.restlet.extension.XXX的jar文件）可以指定给一方或另一方或两者。这取决于扩展名。

你能告诉我我们试图使用的罐子清单吗？

以下是一个示例pom文件，可用于初始化Restlet项目的依赖项：
